Mostly small changes.

- Fixed broken HTML in edit form that swallowed <BR> tags
- Removed "another one" link in roulette, replaced with "use Reload" message
- show() now has edit=1 by default; changed all calls
- Display last-changed date, author, email when present and edit=1
- Added back pointers at bottom
- Added a copy of the bootstrap script at the end of the file
